Small device for quickly cooling high-temperature gas

The utility model discloses a small device for quickly cooling high-temperature gas. The device comprises a first buffer chamber, a second buffer chamber and a cooling system, the first buffer chamberis connected with an air inlet pipe, the second buffer chamber is connected with an air outlet pipe, the cooling system comprises a box body and a cooling pipeline, the box body is filled with cooling liquid, the cooling pipeline is spirally arranged in the box body, and the two ends of the cooling pipeline are communicated with the first buffer chamber and the second buffer chamber respectively.The rapid cooling device is small in size and can be conveniently connected with a PID detection device, and the concentration of pollutants in the gas can be detected at any time after the high-temperature gas is rapidly cooled. The rapid monitoring can provide basic data for guiding the on-site repair and treatment work, so that the construction informatization is realized, the cost and construction period loss caused b
